U.S. Senate candidate Alexi Giannoulias today launched a new positive campaign ad that features both President Barack Obama and First Lady Michelle Obama.

The 30-second spot also features his mother and workers from DesPlaines suitmaker Hartmarx with each of them noting Giannoulias’ compassion and character.

“You can trust him,” President Obama says in the ad. “You can count on him.”

The ad is the first and only in the nation that features the First Lady endorsing a candidate.
